THEODOR'E KAUFER, OF NEW YORK, N. Y., ASSIG-INOR TO vKAUEER COMPANY, ZINC., OF NEVI YORK, N. Y., A CORPORATION OF MANUFACTURING NEW YORK.

cooxING-srovn ne it `inown that l, THnoDonn KAUFER, a citizen of the United States, residin lat lie-w York, in the county oi Bronx and ,tate or New Yfork, have .invented certain new and useful Improvements in Cooking- Stoves, of which the following is a full, clear, and exact specilication.

T his invention relates to cooking stoves oi the tyue using gas, liquid `fuel or yelecric-.ty as a heating medium, and has for its object to provide compact portable stove oi improved resign and construction which is adapted to cook several different articles of food at the same time. Subsidiary objects are to conserve fuel and increase the scope or usefulness of a stove of this kind. Other cbjects will appear as the description proceeds. rlhe inventiondisclosed herein vas originally presented in my forfeited application filed January 4, 1919, VSerial No. 269,570. Y

The, invention will be'rst hereinafter described in connection with the accompanying drawings, which constitute part of this specilication, and then more specifically defined in the claims at the end of the description.

ln the accompanying drawings, wherein similar reference characters are used to designate corresponding parts in the several views :m

Figure 1 is an elevation of a stove constructed substantially in accordance with this invention.

F ig. 2 is a central vertical section of the same. f

Fig. 3 is a section on the line III-IH of Fig. 2, and l,

Fig. 4 is a section on the line IV-f-IV of Fig. 2.

rlhe invention comprises essentially a base section 1 having` air intake openings 2 therein and provided with brackets 3 for supporting a water pan or reservoir 4, and other brackets 5 for supporting aburner or heater 6. lVhile a gas burner is shown in the drawings, it will be understood that other forms of burners or heaters may be used interchangeably therewith, such as oil or alcohol burners or electric heaters, the specific form of the burner or heater constituting no part of the present invention. v

The base section 1 is inthe form of a shell Specification of Letters Patent.

and is preferably round .in horizontal Section with cylindrical walls extending upward from a flared bottom portion, as shown. The water pan orreservoir 4' has a lilling nozzle 7 arranged outside of the base section 1 and extending up to the water level in said receptacle or pan, the upper end of said nozzle being flared or cup-shaped so that the level of the water in the receptacle may be ascertained' by observing its level in the nozzle. f

The burner 6 is preferably provided with upstanding lugs 8 for supporting 'a woven wire frame 9 on which the flames from the burner play. The base section 1 of the stove shell preferably terminates slightly above the level of the frame 9, and the upper edge of the walls of' said base section has formed therein a series of spaced bayonet slots 10 to receive locking pins or rivets 11 on the lower edge of a supplemental shell section 12, which is cylindrical in form and forms a continuation of the walls of the base section. Any number of supplemental shell sections or" any suitable height may be superposed one upon another to build up the shell of the stove yas desired. In the drawings, two such supplemental sections 12 are shown, each having an inset lower flange 13 carrying the pins or rivets 11 and a circumferential shoulder 14 above said inset flange to seat upon the upper edge of the section immediately below it.

A top section 15 has an inset flange 16 carrying pins or rivets 17 to engage the bayonet slots 18 in the upper edge of the uppermost supplemental section 12, it being noted that each of' said supplemental sections has similar bayonet slots. rlhe top section may be of any desired or ornamental shape and has its upper surface 19 provided with a series of comparatively small openings or perforations V20. An upstanding flange 21 surrounds the upper surface 19 :tor retaining dishes or utensils which may be placed thereon for keeping their contents warm.

Inside the shell of the stove, which is built up as already described, a superimposed series of cooking vessels is placed in spaced relation to the walls of the shell, as illustrated in F ig. 2. rlhe bottom vessel 22 rests upon the wire frame 9, while the other vessels 24 have reduced lower or bottom portions 23 to setrdown in the upper endsof the vessels immediately below. Ciroumferential shoulders 25 at the upper ends of the reduced portions 23 of the upper vessels rest on the upper edges of the vessels below, the

walls of all the vessels being preferably in vertical alinement. The number ofcooking vessels used may,'of course, be varied to sult requirementsyand vthe upper edge of each. is preferably provided with an ,inwardly l turned bead 26 to strengthen it.

able material on its upper face, as shown at 29, Fig. 2, saidstone being useful for cookn ing batter' cakes or the like when the top section 15.is removed from the outer shell of. the stove( ln operation, the heat generated by the burner and confined by the outer shell of the stoveiacts first upon the bottom` cooking vessel'22 and then travels upward through the superimposed vessels 24, thus cooking the contents of allof the vessels. Y When the heat' units reach the top of the stove they are turned back by the top surface 19 and travel down along the walls of the shell until they strike the surface of the Water in the reservoir ll, and convert some of it into steam which rises again with the heat units. The

Water reservoir not only permits the forma tion of steam to aid in the' cooking operation, but also prevents the bottom of the stove or the surface on which it may be placed from #1 beingburned out. During the heating operation, fresh air is taken in to support combustion through the openings in -the base l. VThe openings or perforations 2O in the top surface of the section'l serve to permit the escape of dead heat.

l claim: Y

l. In va cooking stove, the combination with an outerl shell composedV of a ringshaped base section and a separable ringshapedv section superposed uponV said base section, of a water container removably supported in said base section, a burner removably supporte'd in theibase section directly over said water container, lugs on said burner projecting above the top surface thereof, a perforated frame removably supportedover the burner onjsaid lugs, and a cooking vessel supported on said frame inside the upper section of the shell and over the burner, Y Y

2. InV a cooking stove, the combination with an outer shellpof a heat-generator therein, va cooking vessel supported in the shell over the heat-generator, a cover for said vessel having a griddle on its upper surface, and aremovable cover for the shell adapted to inclose the vessel cover and griddlewhen the latter is not in use.v

3.1n a Cookino stove, the combination with an outershel of a detachable top section for the shell, .a heat-generator in said shell, a cooking vessel supported in the shell over the heat-generator, and a cover for said vessel having a layer of soapst-one on its upper surface torserve as a griddle when the top section ofthe shell is removed.

. In testimony whereof I have signed my name Vto this specification.
